WAGON-JACK.

Specification of Letters Patent.

Patented April 17, 1906.

Application filed October 9, 1905. Serial No. 282,056.

To all whom it may concern:

Be it known that I, ANDREW J. SHAMBLIN,

a citizen of the United States, residing at Muldrow, District No.11,.Indian Territory, have invented certain new and useful Improvementsin IVagon-Jacks, of which the following is a specification.

The object of my invention is to provide an improved jack designed foruse with wagons and arranged so that it may be used with equal facilityto raise either the rear axle or the front axle when it is desired totake off the wheel or to grease the axle or for any other similarpurpose.

The invention consists, essentially, in a wagon-jack possessing novelfeatures of adjustability and reversibility, as will be hereinafterfullyset forth and as specifically pointed out in the appended claims.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreflecting the result reference is to be had to the following descriptionand accompanying drawings, in which Figure 1 is a perspective view ofone embodiment of my invention. Fig. 2 is a side elevationof theinvention. Fig. 3 is a similar view of a modification. Fig. 4 is adetail perspective view illustrating parts of the modified form.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The post or standard 1 of my improved jack is provided at both ends witha foot 2 for its steady supportand is also provided along one edge withtwo sets of oppositelydisposed ratchet-teeth 3. Fulcrumed on the post 1at a point offset from the middle thereof is a lever-bar 4, which isshown in Fig. 1, secured to the post by means of a pivot or stud 5. Thenose 6 of the lever-bar projects beyond that edge of the post orstandard 1 which is opposite the toothed edge of the same, and the otherend of the lever-bar is provided with a suitable handle 7. Between itsends said lever-bar is provided with a strut or pawl 8, which ispivotally secured thereto at one side, so that it is positioned inalinement with the toothed edge of the post or standard 1, and saidstrut or pawl 8 is designed to engage with any tooth of either set ofteeth to hold the lever-bar in adjusted position after it has raisedeither axle.

In the operation of the device if it be desired to raise the front axle,which, as is well known, is ordinarily in a lower plane than the rearaxle of a wagon, the post or standard 1 is placed adjacent to the axle,with that foot upon the ground which will bring the lever below themiddle of the post. The nose of the lever-bar is then insertedunderneath the axle, and by bearing down upon the handle 7 the said barwill raise the axle to the desired height, whereupon the pawl or strut 8is turned into engagement with one of the teeth of the series which isthen uppermost, and the lever-bar is thus held rigid with the axleraised. To raise the rear axle, the post or standard is reversed end forend, and the strut or pawl 8 is also swung around or reversed on thelever-bar to engage in one of the other series of teeth, as may bereadily understood. I

In the modification shown in Figs. 3 and 4 the pivot-stud 5 whichconnects the leverbar 1 to the post or standard 1*, is provided with aflattened shank 9, designed to take in the longitudinally-extendedportions 1.0 of keyhole-shaped slots or guides 11 in the lever-bar 1,whereby by proper adjustment, as will be readily understood, the saidleverbar may be adjusted longitudinally on its supporting-post 1*, so asto bring its nose 6 to a greater or less degree in advance of theadjacent edge of the said post, thereby changing the fulcrum-point ofthe lever-bar whenever desired. In the same manner the strut or pawl 8may be mounted on the lever-bar 4 with a fiat-shank pivot andkeyhole-shaped slots or guides in the pawl, so that it may also beadjusted longitudinally upon the leverbar to compensate for theaforesaid adjusted position of the latter.

As shown in the drawings, I may secure to the outer end of the lever-bara hook 12 and provide a chain 13, having links designed for detachableconnection with the hook and formed at the outer end with grappling armsor hooks 14, as shown. By this attachment I may use the jack as awire-stretcher or a fence-hoister for hoisting the rails of fences inthe operation of repairing the same or for any other purpose, and whenit is desired to use the device as a wagonjack the chain may bereadilydetached. Any link of the is claimed as new is 1. A wagonjackcomprising a post or standard, reversible end for end, and pro videdwith two series of oppositely-disposed teeth, a lever fulcrumed to saidstandard at a point offset from the middle thereof and having alongitudinally-adjustable connection with said standard, and areversible pawl mounted on said lever and having alongitudinally-adjustable connection therewith.

2. A wagonack comprising a post or standard reversible end for end andprovided with two series of oppositely-disposed teeth, a lever fulcrumedon said standard at a point offset from the middle thereof and providedwith a keyhole -slot comprising two pivot portions and a contractedguideway connecting the two, a pivot-stud secured on said standard andprovided with a flattened shank designed to slide over said guideway andturnable in either of said pivot portions, and a reversible strut orpawl designed for engagement with either series of teeth and providedwith a similar keyhole-slot, the lever-bar being provided with a studhaving a flattened shank designed for the accommodation of thekeyhole-slot of said pawl.

In testimony whereof I afliX mysignature in presence of two witnesses.

ANDREW J. SHAMBLIN.
